SSRS – Disabling export options (eg. PDF) for individual reports-Collection of common programming errors

We have many reports which we use on the website. While exporting some reports as PDF, the file size gets huge and the server crashes due to load. So it would be great if I can disable export to PDF option only for certain problematic reports.

So is there a way to disable certain export options (example: export to PDF) in report viewer 9.0 (SSRS), for individual reports?

Thank you.
